HARRY S. HART, OF CHICAGO, ILLINOIS, ASSIGNOR TO RODGER BALLAST CAR COM- PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF MAINE.

CAR CONSTRUGTION.

Application filed October 22, 1923. Serial No. 669,928.

To all whom it may concern:

Be it known that I, HARRY S. HART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Car Construction, of which the following is a specification.

The present invention relates to car construction.

More particularly the present invention relates to a construction of railway dump cars commonly known as maximum capacity dump cars.

The present invention has reference to dump cars which are so constructed as to permit dumping between the trucks forming part of the car andupon which the car body is mounted. In certain types of dump cars for this purpose the end portions of the car over the trucks are not utilized to their full capacity. I

An object of the present invention is to provide a construction of railway dump car a which utilizes to a very considerable extent all of the space available within the overall dimensions of the car.

A further object of the present invention is to provide a railway dump car so arranged that the end portions over the trucks may be utilized for the carrying of lading which may be conveniently dumped laterally of said trucks. 4

A further object of the present invention is to provide a construction which may, with a minimum of reorganization, be applied to railway dump cars as now designed for the purpose of increasing the capacity for lading while retaining the advantages of convenient side dumping for all of said lading.

Further objects will appear as the description proceeds.

Referring to the drawings:

Figure 1 is a view in side elevation of a railway dump car embodying the principles of the present invention;

Figure 2 is a top plan view of the car shown in Figure 1;

Figure 3 is a sectional view taken along the plane indicated by the arrows 33 of Figure 1; and

Figure 4 is a sectional view taken along the plane indicated by the arrows H of Figure 1.

' Numeral 1 indicates a railway dump car having the side walls 2, 2. The car 1 is supported at or near its two ends by trucks 3, said trucks being indicated by the wheels 4:, 4 thereof. Mounted between the trucks is the hopper portion 5. Mounted longitudinally of the car is the center sill 6 which, in the illustrated embodiment, is of the selfcleaning variety. Said center sill has connected thereto the sloping bottom Walls 7, 7 for directing lading laterally from the region" of the center sill 6. Mounted adjacent to the side walls 2, 2 are the bottom sloping walls 8, 8 which direct ladingtransversely of the car from'the regions of the side walls 2, '2. Swingingly mounted about the'axes 9,- 9 are the dump doors 1O, 10 which are controlled by the link mechanism indicated as a whole by the numeral 11, which link mechanism is in turn'controlled by the longitudinally extending shaft 12.

-Said doors 10, 10 form closures for the hopper'p'ortions formed by the sloping bottom walls 7, 8. It will be clear without detailed explanation that when the shaft 12 is rotated in a direction to cause the link mechanism 11 to open the doors 10, 10, lading from within the car 1 will be directed to a region midway of the tracks upon which the car is mounted. Said doors 10, 10 are provided with intermediate doors 13, 13 swingingly mounted about axes 14c, 14 extending longitudinally of the car. Said intermediate doors 13, 13 are controlled by chains 15, 15 which may be controlled by shafts 16, 16 extending longitudinally of the car. As noted above, the dumping mechanism, including the sloping walls 8, 8, the sloping walls 7 7 the doors 10, 10, the operating mechanism 11, the intermediate doors 13, 13, and the operating chains 15, 15, all comprise dumping mechanism for 'depositing lading from the car between the trucks thereof. 7

The numeral 17 indicates a transverse sloping bottom wall for directing lading to the hopper portion 5. One of said slo-plng bottom walls is provided at each end of the hopper portion 5, each having preferably a straight upper edge. Located at the level of the upper edge of the corresponding sloping bottom wall 17 is the floor 18 located above the trucks. The numeral 19 indicates as a whole, operating mechanism for the dump doors of the hopper 5, which operating mechanism is located at the end of the hopper 5 below the sloping bottom wall 17 whereby said sloping bottom wall directs the lading in such a direction that said lading in being dumped will not intert'ere with the proper functioning of the operating mechanism 19.

The fact that the floor 18 above the trucks is at a level corresponding to the upper edge of the sloping wall 17 has certain adyantages inthat the floor lS and sloping bottom wall 1'? at each end of the car cooperate etlectively-with the hopper 5 to provide a car Which may conveniently be completely; dumped inasmuch as no pockets are provided for the undesirable lodgment of said lading.

The fact that the floor 18 is located on a level with the upper edge of sloping bottom wall 17 has the further advantage that room is provided above the trucks 3 for swinging movement of the doors 19, 19 which are pivotally mounted about the longitudinally extending axes 20, 20. Said doors 19, 19 may be held in horizontal or closed position by any preferred means, swinging links 21, 21 having been illustrated as examples of such holding mechanism. Figure 2 illustrates four of the swinging doors 19, 19, which doors are spaced longitudinally on the two sides of the bolster 22. Said four doors at each endof the car provide anextensive opening for the corresponding floor 18 whereby, with a minimum of shoveling, lading in the portion of the car over the trucks may be completely deposited laterally of the car.

Though a preferred embodiment of the present invention has been described in detail, it will be clear that many modifications will occur to those skilled in the art. It is intended in this patent to cover such modifications that fall within the scope of the invention as defined by the appended claims.

I claim:

1. A dump car having trucks located near the ends thereof, dumping mechanism intermediate of said trucks, a sloping bottom wall.gliavina substantially straight upper edge adjacent to each of said trucks for di reotinglading to said dumping mechanism and a flat bottom wall at the level of the upper edgeof said sloping bottom wall, said flat bottom wall being provided with downwardly swinging doors for directing lading laterally of said trucks.

2. A dump car, including dumping mechanism for dumping intermediate 01 the length of said car, a sloping bottom wall. at each end of said dumping mechanism for directing lading to said dumping mechanism, each of said bottom. walls having a substantially straightupper edge, and a flat bottom wall coinciding with said edge, said flat bottom wall including downwardly and outwardly swinging walls for directing lading laterally of said car at the ends thereof.

Signed at Chicago, Illinois, this 17th day of October, 1928.
